A little over a week after the last episode of Sonic Highways aired on HBO, we find Foo Fighters still heavily promoting their documentary and their most recent album of the same title worldwide.

Set to embark on a massive world tour, hitting parts of South America, Europe, and North America starting in January, the rock icons made a few stops on a couple late night shows, with the most recent being The Tonight Show Starring Jimmy Fallon.

On last night’s episode, the Seattle quintet graced the audience with a performance of their song “I Am A River” off of Sonic Highways. The band was accompanied by a full string orchestra and it resulted in a majestic performance.
